Problems solved by technology

[0002] Since the traditional hydraulic power steering system used on the vehicle is only controlled by mechanical transmission, its power-assisted characteristics cannot be adjusted and controlled during the working process, and it is difficult to coordinate the contradiction between the lightness of the car steering and the road feeling. The pump works under the drive of the engine, which wastes fuel and reduces the fuel economy of the vehicle

Embodiment Construction

[0040] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0041] The invention provides an electronically controlled hydraulic power steering control method, which is used for the control of a hydraulic power steering system on a vehicle. Such as Figure 21 As shown, the hydraulic power steering system is mainly composed of high-pressure oil supply pipe, oil return pipe, power steering pump assembly, steering gear, steering control valve composed of four valves, and power cylinder. The oil supply volume of the valve and power steering pump assembly is determined. The power steering pump assembly supplies working pressure oil to the pressure oil circuit ...

Abstract

The invention discloses an electrically-controlled hydraulic power-assisted steering control method. The method adopts a power-assisted steering pump assembly which mainly consists of an electric motor and a hydraulic pump; the hydraulic pump is driven by the electric motor to run and supply working pressure oil fluid to the oil pressure line of a steering system, and whether control signals are output to the electric motor or not is determined according to steering parameter signals obtained in real time, wherein the electric motor is electrically connected with a controller through a driving bracket. The electrically-controlled hydraulic power-assisted steering control method disclosed by the invention adopts the electric motor to drive the hydraulic pump to run, and the working states of the electric motor can be controlled in real time, so that the energy waste is fundamentally reduced; the electrically-controlled hydraulic power-assisted steering control method has a good energy-saving effect, so that the fuel economy of a whole vehicle is improved, and the driving safety and the driving comfort are improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle steering systems, in particular, the invention relates to an electronically controlled hydraulic power steering control method. Background technique [0002] Since the traditional hydraulic power steering system used on the vehicle is only controlled by mechanical transmission, its power-assisted characteristics cannot be adjusted and controlled during the working process, and it is difficult to coordinate the contradiction between the lightness of the car steering and the road feeling. The pump works under the drive of the engine, which wastes fuel and reduces the fuel economy of the vehicle. Contents of the invention [0003] The invention provides an electronically controlled hydraulic power steering control method, with the purpose of realizing energy saving and improving the fuel economy of the whole vehicle. [0004] In order to achieve the above object, the technical solution adopted by ...
